Latency Test

A simple tool to measure network latency and response times.

Features

• Measure latency to a given target (IP or hostname)
• Support for REDIS, PostgreSQL and Kafka
• Customizable interval and timeout settings
• Logging and reporting capabilities

Installation

Prerequisites

Ensure you have the following dependencies installed:

• curl
• librdkafka-dev
• libpq-dev libhiredis-dev
• gcc
• default-jre

Compile the project

git clone https://github.com/mulatinho/latency-test.git
cd latency-test
make && make install

Usage

Basic Example

./check-latency [postgresql|redis|kafka] <host> <port>

export PGUSER=youruser
export PGPASS=y0urpass
./check-latency postgresql 127.0.0.1 5432

Example Output

$ PGUSER=yourus3r PGPASS=p4ssword ./check-latency postgresql 127.0.0.1 5432
